Title: Detection method for fruit and the like
Inventor: NAGAI HIROSHI
IPC: G01N21/17
Filed: 1989-10-06
Abstract: PURPOSE:To take out only the video part of a fruit by binarizing difference between the maximum density value and an minimum density value of the density histogram of an object such as the fruit, etc., as a binary reference density value, and varying this binary reference density value. CONSTITUTION:The image of the object is fetched by a camera 1, and a red R, a green G, and a blue B signals of each image are stored in an image frame memory 3 for R, G, B signals storage through an input interface 2. For instance, in the case of a tomato, the image density histogram is calculated by etching only the R signal into a CPU from the memory 3. The difference between the maximum density value (Hmax) and the minimum density value (Hmin) is obtained in this histogram. The image is binarized by the binary reference density value (y)=alpha(Hmax-Hmin) as varying a coefficient alpha to convert and adjust this difference up to 1 excepting 0, and the fruit is detected. Thus, by providing the coefficient alpha to enable to vary the binary reference density value to binarization-process the image, the video part of the fruit can be distinguished from a part other than the fruit, and the detection precision of the fruit can be improved.

IPC: A61M29/02
Filed: 1997-08-21
Abstract: PROBLEM TO BE SOLVED: To stop insertion and shape restitution and recover easily when an indwelling shape abnormality occurs, by providing ring recovery sections on both ends of the frame in an intravascular indweller intended for hemostasis, constriction control, and thrombus movement control by making a catheter indwell intravascularly. SOLUTION: An intravascular indweller is formed by providing a recovery section 2 at one or two ends of the frame 4 of an intravascular indweller. To use it, the frame 4 is wound around an insertion catheter and a fixing line is run to the clearance of the frame 4 and the recovery portion 2 and fixed to the insertion catheter. Then the insertion catheter is advanced along a guide wire and stopped at an intended portion. By pulling the fixing line extracorporally, the frame 4 is separated from the insertion catheter by it's own restitutive force and is retained intravascularly. To stop the restitution of the frame 4 and remove it extracorporally, the frame 4 is removed extracorporally by stopping pulling of the fixing line and pulling the insertion catheter extracorporally.

Filed: 1999-09-17
Abstract: PROBLEM TO BE SOLVED: To efficiently detect an abnormal part of an image when the image has a background with many variations by deciding abnormality of the original image by using a gradient image. SOLUTION: The gradient image is generated from the original image. The gradient image is characterized by that the values of its pixels are the judgement indexes of the gradients at the corresponding position in the original image. A blur gradient image is generated and a ternary image is generated from the gradient image and blur gradient image. A binary image is generated and a series of closed outlines is extracted from the binary image and registered in a 1st abnormality candidate list. So that each pixel of the original image is encircled with one outline, outlines in inclusion relation are removed and a 2nd abnormality candidate list is obtained. A detection test is applied to the 2nd abnormality candidate list and outlines which are considered to show the state of the real digital image are excluded from the list.
